Why Clint Dempsey is ill-fitted to drive new USMNT attack

Is it time to for Jurgen Klinsmann to remove Clint Dempsey from the USMNT's starting lineup? 

A quick glance at Clint Dempsey's stat line from the U.S. men's national team's 2-0 loss to Colombia on Friday night would seem to indicate that he wasn't a problem. He tallied seven shots, including a header cleared off the line and a free kick that forced Colombian keeper David Ospina into an excellent diving save.
